Abstract
Objectives: Hypoglossal nerve stimulation (HNS) is a treatment option for patients with moderate-to-severe obstructive sleep apnea. In the post-implant period, awake endoscopy with advanced programming (AEAP) can be employed to improve apnea hypopnea index (AHI) reduction and/or patient comfort. This study describes response patterns to HNS after AEAP as well as patient-specific patterns in our patient population.
Methods: Retrospective evaluation of 17 consecutive patients who underwent AEAP between June 2019 and December 2022. Post-AEAP AHIs were used to create 2 response groups, which facilitated analysis of patient-based characteristics. AHI reporting, deemed non-titration AHI (NT-AHI), is the whole-night AHI resulting from non-titration studies. Chi-squared, Pearson correlation coefficient, and independent samples t-test were used to determine significance deemed as P < .05.
Results: Fifteen of 17 patients (88.2%) presented for failed NT-AHI reduction, and 2/17 (11.8%) presented for comfort measures. Eleven patients (65%) showed an improvement in post-AEAP NT-AHI; 6 (35%) patients failed to improve. Four patients with either lateral wall collapse or concentric wall collapse at the tongue base failed to improve NT-AHI compared to a single patient who showed an improved NT-AHI (P = .017). Of the 2 patients who presented with discomfort, patient 1/2 demonstrated improvement in device usage, and patient 2/2 reported improved comfort while maintaining average device usage.
Conclusion: AEAP is a powerful tool that offers the ability to identify settings conducive to increased therapy efficacy and improved treatment tolerability. Airway phenotypes are closely correlated with treatment efficacy, and as such, careful anatomical consideration of the upper airway must be performed when titrating therapy.
Lay summary: Amongst the different treatment options for obstructive sleep apnea, hypoglossal nerve stimulation has been shown to be effective in positive-airway-pressure intolerant patients. This article explores response patterns to AEAP and highlights the importance of careful anatomical considerations of the upper airway.
期刊介绍：
The Annals of Otology, Rhinology & Laryngology publishes original manuscripts of clinical and research importance in otolaryngology–head and neck medicine and surgery, otology, neurotology, bronchoesophagology, laryngology, rhinology, head and neck oncology and surgery, plastic and reconstructive surgery, pediatric otolaryngology, audiology, and speech pathology. In-depth studies (supplements), papers of historical interest, and reviews of computer software and applications in otolaryngology are also published, as well as imaging, pathology, and clinicopathology studies, book reviews, and letters to the editor. AOR is the official journal of the American Broncho-Esophagological Association.
